WWE Royal Rumble 2015: 10 Reasons The Undertaker Might Return

7. To Set Up A Rematch With Brock Lesnar

Most will argue that there is no need to see Lesnar Taker 2 at Mania 31, but it is a road that WWE could feasibly go down. Lesnar's schedule and involvement in the WWE World Heavyweight Championship picture probably means that a rematch can't happen, but as the outcome of the first match was decided roughly four hours before the show began last year you can't rule it out. How WWE would work another compelling angle between the two would be tricky. Realistically, Taker has nothing left to fight for after his streak was taken away from him last year while why would Lesnar want to step back into the ring with The Phenom after conquering the streak and winning the title belt?
